Efficacy and Safety of Amyloid-Beta Directed Antibody Therapy in Mild Cognitive Impairment and Dementia with Evidence of Both Amyloid-Beta and Vascular Pathology (U01 - Clinical Trial Required)

This RFA will solicit applications for a pivotal phase 3 clinical trial to determine the efficacy of FDA approved monoclonal antibody therapy compared to placebo in diverse "mixed dementia" populations with a focus on vascular contributions. Mixed dementia refers to dementia cases positive for 1) Alzheimer biomarkers, such as amyloid positron emission tomography and/or low cerebrospinal fluid amyloid beta 42 combined with elevated phosphorylated tau; and 2) evidence of vascular contributions based on imaging (white matter disease and/or subclinical infarction). Bayesian approaches with response adaptive randomization to examine specific subgroups are engouraged. Successful applications will be well-powered to determine efficacy in diverse populations representative of the effect of the disease in the United States by sex, race/ethnicity, and geographic distribution. Applications must include patient and community engagement cores that are incorporated into all stages of program development and at all levels of the organizational structure.
